(a): the accelerator pump is in the top of your carburetor, - "(see picture) depending on what carb you're running. It's long, thing, has a spring (i think) and a plunger-type thing at the end of it.
(b) What engine / carb do you have?
(c) the "Psssh" sound ... Hmm.. have you checked all your vacuum connections? That'd certainly cause a hesitation I think if one's not connected ... let us know!
